Is it okay for a woman to propose to a man?

Could you please ask your followers if they believe it is okay for a woman to propose to a man. The reason I am asking this is that today I and my cousin were watching the reality TV show Love and Hip Hop and one of the ladies on the show proposed to her love interest. My cousin then said ''she has no self respect''. I was rather shocked because my cousin is female and I did not expect this from her. My point is that, it is the 21st century. I do appreciate that not everyone and even some females do not believe in gender equality but I just want to understand why this is such a big deal.
